Introduction to IRC - SAHANA-EDEN

The activities on #sahana-eden were quite limited. The group seems to be more active on https://groups.google.com/forum/#!forum/sahana-eden --Rmezei 23:44, 9 May 2014 (UTC)

SAHANA EDEN Project

As part of POSSE 2014, I would like to work with the SAHANA - EDEN HFOSS project. I will post some of my findings on my blog. [1] --Rmezei 17:07, 9 May 2014 (UTC)

FOSS Field Trip

——————– SourceForge.net ——————–

On http://sourceforge.net/ I searched for Mathematics projects and found 749 projects corresponding to the category of Mathematics. There were at least 15 different programming languages used for writing those software projects.

The most common programming languages used were: C++ (206), Java (155), C (111), Python (78), Matlab (31), C# (30), S/R (26), JavaScript (19), Fortran (16), Lazarus (11), VB .Net (11), Delphi/Kylix (10), Basic (9), Perl (9), Tcl (7) .

The most popular project for the Mathematics category was: “gnuplot development” ( http://sourceforge.net/projects/gnuplot/?source=directory ). It had scored 11883 weekly downloads. The software does 2D and 3D plotting, and supports a “huge number of output formats” as well as “interactive input or script-driven”. I believe this project will most likely be used by scientists who want to express their work/ideas using 2D or 3D images. The primary programming language was C and the most recent change was made on February 23rd, 2014 (Gnuplot Version 4.6.5).

According to http://www.ohloh.net/p/gnuplot the project has 4 contributors in the last 30 days. Although I would love to get involved into developing this project, I wouldn’t necessarily use it on a daily basis. The main reason behind this statement is the fact that the user interface is not really updated to today’s standards.

Mifos project was mostly written in Java (33%) and Php (21%). It has 2.677 million (Apr 2014) lines of code. The locations for some of the contributors include:

• Collegeville, Philadelphia, PA, USA
• Minneapolis, MN, USA
• Bangalore, India
• Lausanne, Switzerland
• Helsinki, Finland

There are about 19 programming languages used for Mifos, including: Java, XML, PHP, HTML, JavaScript, SQL, CSS, Python,… The language with:

• the second highest number of lines of code was XML (515,397).
• the highest comment ratio was Perl (28%)

In the last 12 months, the project had:

• about 10 contributors (0 since last October)
• 162 commits

The top three contributors to the project have been involved with Mifos for about 1 year, 1-2 years, and about 1 year respectively.
